tecl'iments that ere not employed in those shove, which attachments will he described later in the description of the` operation. Euch cylinder A has s discharge pipe 8, leading from its upper end downward into the interior of the cylinder und terminating neer the bottom thereof. rihe lower end of euch pipe 3 is provided with e foot valve fl, of the ordinary liep vulve ty e, which opens upward, or any other suitab e valve may be employed. Each pipe 3 connects at its upper end with the conducting pipe 2, which lends upto and connects with the lower end ci' the next cylinder shove, or in the cese of 1 connecting with the upper end of each o the cylinders A in the series, for the purpose of 'admitting air under pressure to the cylinders, later described. A vent pipe "i connects With the top of euch of the cylinders A., except the lower cylinder, and is disposed parallel with lLhe. air feed pipe A. suction pipe 8 connects with the lower cylinder A, and u. vacuum tank 9 situated neer the mouth of the well, or shaft through Which the sir in the lower tenir A may be drawn ofi `(ind e vacuum crested. therein. y

i (jut-ofiQ valves lO-l are provided in the pipes 5-8 or 5-'-7, respectively, it a point near their connections with the cylinders A, and are so disposed that the plugs 'of the vulves lO--ll muy he joined together by a bur or rod 12 extending from one valve to the other, so as to permit the valves lO-ll to rete in unison. These vulves l0-l1, while operating in unison, perform oppositev `functions, that is to say, the vulve l() is open to the airr line 5 While the valves il ure closed to vthe vent pipe 7 und vacuum pipe 8. Any suitable type of vulve may he used. .i supplementary cut-ott valve 13 is disposed on the end of the pipe Where it extends into' e cylinder A, which is designed to be automatically opened und closed independent of the valve l() thei'eehove. This is accomplished by ineens of u, floot 14, suspended. by u cord le from e lever on the vulve plug,` the '.tlout operi i the valve as it rises and closing it as ills. The upward movement ci? the .il is limited by e chain 16 above by means oi a piston 18 in a cylinder.

18 operated from the compressed air suply 6. A crank 19-`-19 is mounted on each Yalve 10-11, and a cord 20-20, connect-ing with 'cach crank 19-19 leads upward to the top of the well or shaft a'nd .is attachedl to cranks on a crank shaft 21, which in turn is connected to the rod of' the piston 18 by a crank arm 22, and a link 23, in such inanner as to transmit a rocking movement to the crank shaft 21 as the piston 18 reciprocates. The link 23 is pivoted at one end to the rod of the p iston 18, and is connected to the crank arm 22 by means of a pin 2a on the latter, which extends through a slot 25 on the upper end of the link 23, as shown iny Fig. 5. A weighted arm '26 is so mounted on the crankshaft 21 that when the shaft is rocked or turned from side to side by the piston 18, the weight 26 will pass from one side of the center of the shaft 2l to the other,I and on passing` to either side will cause the movement ot" the shaft 21 to quicken, which movement is permitted by the slotted connection between the crank arm 2Q and the lilik 23. v

The operation ot' theI invention is as jt`ollows: Assume the cylinders A to be empty,

that is containing no fluid, but air, and the lowermost cylinder in contact with the liquid to be pumped; water being'the commonest liquid will he spoken of as the medium being handled. A normally closed foot valve st is provided on. the lower end of the lower tank or cylinder A or'on a pipe Q extending downward therefrom. This valve 4 must be submerged in the water to be pumped. The valve l() on the air pipe 5 above the lower cylinder A being closed. the valve 11. on the vacuum pipe 8 is open. The air in the lower tank'A can new be drawn outI through the vacuum pipe 7, which action creates a suction in the lower cylinder A, causing the water to he drawn through the 'foot valve 4 into the interior of the cylinder until the valve 11 is closed. This is accomplished automatically by means of a Host 2G mounted on a crank ou a sha lt. 27 extending through the upper portion ot' the lower cylinder A., in such manner that as the float 3G is lifted by the water in the cylinder A it will rotate the shaft 2T. Crank arms 2S mounted on the shaft 2.7 exterior ot' the cylinder A rotate with the shaft 27 and act upon cords 2.9, which extend upward to the top of the shaft and connect with a crank shaft 30, to rotate the latter in unison with the shaft. 27 in the lower cylinder A. rlhe outer end of the crank shaft 30 connects with an ordinary admission valve 31, which is disposed in the air supply pipe leading from the reservoir 6 to the cylinder 18. As the crank shaft 30 is revolved by the float on the shaft 27, the valve 31 is opened to admit air under pressure to the cylinder 1.8', which causes the piston 18 to rise and rot-ate the shaft 21 to close the valve 11 and open the valve 10. The opening of the valve l0 admits air under pressure to the lower cylinder A above the water therein, which forces the water downward in 'the cylinder and upward through the t'oot valve 4 into i.

thepipes 3-2, the foot valve 4 on the lower tank closing to prevent the water returning to the well. feter is thus conveyed from the lower cylinder A' to the next cylinder above, the vent valve 11 in this cylinder being open to allow the air in the cylinder to escape while the water enters the lower end of the cylinder from the pipe 2. The second cylinder A becomes filled the moment the lower cylinder empties, and as the ,loat 26' falls and operates the valves IGf-ll, through the piston 18, es before described, the vent valve 11 is closed and the air inlet lvalve 1Q is opened so as to admit air under pressure to the second cylinder A, which forces the water therein upward through the pipes 3-2 to the nextcylinder above, and so on until the wateris discharged.

From t-he'foregoing, it will be seen that the cylinders operate in' pairs, one emptying while the other is filling. In order to admit of this alternate action it is necessary that the valves 10 he connected to the cord Q() in such manner thatl adjacent valves will he operated alternately, that is, one valve remaining open while the next one adjoinl ingl is closed. The valves 11 will, of course, be mounted and operated in a similar manner.

As a means of preventing the float .26 dropping so as to operate the valves 10-11 when the water in the lower cylinder A. falls 'below theirl level, a weighted erin 32 is mounted on the crank shaft 30 in such manner as to counterhahince the float 27 and hold it in its uppermost position, and at the same 'time retain the valves 113-11 in their proper relative open and'closed positions. An auxiliary tlost is suspended on n flexible cord from the float 2G', and

is limited in its upward movement bya chain' li 'il his tioat is weighted so as to overbalance the weighted arm S2, and when,

the water inthe lower tank A falls below the weighted that 52? the latter moves down` wardly, pulling the tloat E27 back to its lowermost position und throwing the weighted arm 32 to the opposite side ot' the center of the shaft 30 in the saine manner as that descrihedin relation to the weighted crm 26 pipe 5 in each of the cylinders A is provided for the purpose of shutting otf the incoming air at a moment when the water in the cylinder is forced downward to a certain level, thus preventing the water being fdrced below the foot valves 4.

llt is obvious that the cylinders A may be disposed horizontally instead of vertically, Where the width of the shaft will admit. n this' case the invention would be constructed in the form shown in Figs. (i and s; 7, in which the air supply and Vent pipes 1 would lead to a dome B on the cylinders A, and the crank shaft 27 and float 26 would be mounted therein. The foot valve on the pipe 3 would extend into a pocket or trap C on the under side of the cylinders A, and the upper ends of the pipe 2 will connect with the pocket C at the lowest point. This pockctor trap C admits of the tank A being emptied without unsealing the valve 4.

lNhere the invention is applied to wells having narrow casings, the cylinder A may be constiaicted as shown in Fig. 8, in which form the air pipes 5 and vent pipe 7 pass through the interior of the cylinder A, thereby not taking up so much room as in the con-` structions previously described.

In practice, the lower cylinder .A in the series, is connected to the cylinder above Yby flexible connections, anda portion of the air pipe and vacuum pipe adjacent the lower cylinder can also be ilexible so as to admit of the lower cylinder being- Vraised or low.- ered. A block and tackle arrangement is provided, whereby the position of the lower cylinder may be adjusted and raised or lowered to a desired degree. In the event the lower cylinder A can be wholly submerged in the water, the vacuum tank S) can be dispensed with if desired as the water would flow into the cylinder through the valve 4 and seek its normal level therein. The tanks are preferably spaced at equal 'distances apart so that even air pressure will operate each tank alike and thereby produce a uniform flow or discharge from the pump. Each tank in the series may be a tride larger in size than the next one below so as to insure it containing all thc charge delivered therefrom, and the appaiatus may be worked at any angle by connecting the pipes to the tanks at advantageous points. 'As the air piston 28 is supplemental power for actuating the valves itl-l1, it is obvious lthat electric or steam power may be employed for that purpose, and where the floats 2G can be madelarge enough to operate the valves, supplemental power is not required and may be dispensed with altogether'.

When it is desired to use this pump as it is shown in Fig. 6, in a shaft that isin process of sinking, the lower section shown in Fig. l may be used, as it is much casier to lower or extend downward. I Having thus described my invention, what I claim and desire to secure by Letters-Patent, is-
